view - Method to override when layout is destroyed in Android

I have a custom component which extends LinearLayout, I need to execute certain statements when Layout is destroyed or removed. (or about to be removed)

One way is to check for onPause() or onDestroy() of an activity and call methods of the custom component. But I want to remove that overhead from the activity. So that custom component itself can handle when layout is detached. But I dint find the suitable method to override (to detect the event) when layout is removed. Is there a way to handle this, or we need to use onPause() and onResume() method of activity ?

I had success overriding the onAttachedToWindow() and onDetachedFromWindow() methods:

@Override
protected void onAttachedToWindow() {
    super.onAttachedToWindow();
    // View is now attached
}

@Override
protected void onDetachedFromWindow() {
    super.onDetachedFromWindow();
    // View is now detached, and about to be destroyed
}
